Reconfigurable System Design And Implementation Of The Three-tier Architecture Applications

The performance of enterprise information system should have the higher standard because the increase of the corporation's demand has exposed the defect of original system. In addition, with the development of the information technology, we can find more flexible methods to develop enterprise information. So, this paper presents the Reconstructable Three-tier Application System.Firstly, this paper analyzes the deficiency of the traditional development model, presents a method of enterprise application system reconstruction based on our experiences and the current XML, distribute technology. The linchpin of this method is the reconfiguration of business logic.Secondly, this paper summarizes the Reconstructable Three-tier Application System and analyzes the structure of this system. This system is separated two parts: the module of user interface configuration and the module of business logic configuration. We design many controls, institute the attributes and event responses of these controls. We configure the event responses to achieve the enterprise business logic. The events drive the business flows. According to the relationship of events, we design three modules: order module, selection module and loop module. In addition, a XML file format is defined to save configuration file.Finally, we analyze the business flows of Bank-Taxation System. We create the user interface configuration files and the business logic files by the Reconstructable Three-tier Application System.
